Secured Partial MP3 Encryption Technique

The encryption algorithms are applied for giving security to the audio data. Many encryption algorithms have been proposed to meet the security requirements of the different applications. But, lack of application friendliness limits those algorithms from practical implementation. Encryption technique can be applied on the Moving Picture Expert Group Layer III (MP3) audio data before the MP3 compression, at the time of the MP3 compression and after the compression. Here, the authors have applied the Advanced Encryption Standard (AES) encryption algorithm at the time of MP3 compression on the selected quantized audio data.
